Is it possilbe to read codes for a 95 beretta?

I was trying to run codes for my 95 beretta , when i noticed the black ALDL diagnostic connecter only had 2 terminals on it.

There is the A terminal which is on the top right, and one directly below it, and that is it.
I did not try to touch them together, but if i can get some verification i would like to know if this code reading can be done without a scan tool.

Btw, the car runs ok, but when idling, and any load , like the electric fan and or air conditioner start, it needs a foot on the gas to continue to idle.
And finally, for the first time, i saw the service engine soon light, while the car was running. Any suggestions??

Unfortunately you are stuck in the ODB 1.5 debacle. Very few scanners actually read these as it's a mixture of ODB1 codes and some ODB2. You can read a little about it on Wikipedia:

I have a 95 Corsica that I've never been able to read the codes for. I've heard GM Tech 1 will read it, but I've taken it to a few dealers that couldn't do it.

I have a Snap-On MT-2500 scanner that will read and control OBD1, 1.5, and OBDII ECMs/PCMs - Fully bidirectional. Many shops used to possess these as their primary diagnostic tools, and many will probably still have one tucked away somewhere with the correct adapters. Ask around. You might even be able to buy one less expensively than you might think.

I don't think so Blue.....

If you just want to read codes for 1.5I, that will take an upscale high priced scannner to do that, compared to a code reader for OBDII cars, for 20 bucks....

Even GM's Tech I couldn't read them without an adapter....the Tech II can, if you have $2500 hanging around....

Are you sure a Tech 2 will read it? I know a dealer tried a Tech 2 and it didn't work.

Vehicles I've read with the MT-2500:

1995 LeSabre
1994 Impala SS
1995 Blazer, including ABS and TCCM
1995 Camaro
1995 Lumina
1995 Cutlass
1995 Grand Am, including EBCM

Yes, a Tech II can read it.....and i am sure an MT 2500 can also.....

Went to EBay to check on prices for the MT 2500......a lot of prices were in the 600-1000 range, but there was one, in bidding around 100....but I doubt it will stay that low or might be pulled....

Ouch! That's a bit more pricey than I remember. Mine was less than $1K with a ton of adapters, troubleshooting and comm modules, power supply adapters, and the all-important cable.

if your check engine lights works not on but when you turn the key on it luminates there is a real expensive tester that works for all gm obdi take a paper clip unwind it straighten it out bend it in half insert one end into one hole and the other end into the other hole get pen and paper turn key into run engine off position the check engine light will start blinking count blinks beteween a brief pause ++++ +++++++ example 47 +++ +++++ 35 a dodge is a lot easier key on/off 3 times final turn leave in on position a form a old analog meter leads into obd port same a paper clip hope this helps ya

The problem with the jumper method is that it doesn't work with OBD1½ systems. Many GM vehicles in 1994 and 1995 were of that variety. I have a '94 Impala with that type PCM, and had a '95 Buick with that same type. Only a Tech II or MT-2500 would read it.
